Thank you for viewing. This is a bonus from Keroro Land/Keroro Ace, a Sukiya giveaway. It is a used item. The diameter of the light green ball is approximately 3.5mm. The size of the yellow drawstring bag is 13cm x 12cm. The stickers have been partially used, as shown in the image. The Keroro Land memo pad has writing in it, and some pages have been torn out. Thank you.
